更新后无法登录 tomcat 管理器

Question

系统更新后，我无法再登录tomcat。它在更新之前工作，但它不再工作了。不完全确定发生了什么。

OS：拱门linux

Java版本：openjdk 1.8.0_25

当前Tomcat版本：8.0.15

tomcat-users.xml:

  <user username="manager" password="manager" roles="manager-gui,manager-script,manager-jmx,manager-status"/>

</tomcat-users>

manager/manager还是给我未授权。有什么想法吗？

此外，有没有办法查看 tomcat 实例加载的所有用户的列表？

Answer 1

造成这种情况的可能原因有很多：

您是否在编辑文件后重新启动tomcat？
您确定 tomcat 用户对配置文件有足够的权限
尝试为管理员用户添加 admin-gui 角色
